I just "purchased" the plastic bushings for my Galaxie bellcrank/z-bar (frame side), and am disgusted by the price of these little bits of plastic. Are there any here that are familiar with these pieces and if there is a plastic material robust enough for a 3D printer. I have the new bushings and may set up a 3D printer to reproduce--any thoughts?
-
If it's a round bushing, couldn't you get a chunk of appropriate plastic and turn it on the lathe? I did that for the little plastic wheel on the window regulator on my truck because I didn't want to buy a whole new assembly.

That's the way to do it. 3D won't take the load that a stick of Delrin or similar material will take . A screw machine could turn out a hundred in minutes cheaply.

Agree, 3D is not something you want to put a heavy load on.
Depending on the actual OD and ID, you might find it ready to go at places like McMaster Carr?

It is not the round bushing. The ball stud on the bellhousing takes the round-ish bushing that is common on Cougars and Mustangs, but the frame side of a 66 Galaxie there is what I would call a plastic sleeve that wraps around the stud (two pieces). See the link below--sorry, I should've included it in the original post.

I know there are different plastics for printing, I'm just not very familiar with it; a friend of mine just bought a printer to work with and parts reproduction is something we've been discussing.
Hell, I should've carved a piece of hardwood--it would've probably worked just fine..

When I bought my '63 Effie, it used a bracket on the block with the ball you speak of. The previous owner, who'd swapped the '64 390 PI engine in---it had come from the factory as a six---used a bronze split bushing that I found listed as a Thunderbird part. I replaced it while tightening-up the clutch linkage. One put the split bronze around the ball and then pushed the cross-tubing over the OD of the bushing. But three or four months later, I needed to do it again. The ball was damaged to such an extent it simply 'ate' the bronze. I took the bracket off the block and removed the ball. I put a bolt through the hole left, slipped on a washer I made from a piece of bar stock Delrin---drilled the center on my drill-press and then put a bolt and nut through the hole and chucked it up in the DP and used a file on the OD until it fit in the tube. Pushed some grease into the tube for residual lubrication and put it back together. Was still just like that when I sold the truck thirty years later.

That is an excellent solution, one I will keep in mind if I have a bad ball stud. That material would work for this, though obtaining the correct form would surely be challenging.

I've made some in the past with these. Cut the width and drill a hole.

I forget exactly which material I used. It may have been straight Delrin.
